guy puts up crap numbers for most of his career, and then suddenly in in early 30s puts together 3 very solid seasons.
How does that happen?
maturity, better pitching coach, reinvents himself a tad as his ages and loses some velocity- stuff like that
His
PitchFX data goes back seven years to his last (age 28) season in Minnesota. His velocity has been pretty consistent. His average fastball has dropped off by 1 MPH. I don't remember him as a particularly hard thrower with the Twins (and his K/9 numbers don't suggest that he was) but maybe the loss of velocity happened before 2007.
What really stands out is increased use the sinker. He threw 8 in 2007 and 12 in 2008 compared to 1538 in 2011, 1331 in 2012 and 773 so far this year. It's a hard two seamer with average velocity that's almost identical to his fastball. That pitch is Duncan's calling card and Lohse took it to the bank.
I've touted Duncan for the Hall of Fame here before. It's hard to think of another pitching coach who turned so many average pitchers into aces.
